WIRE MATTRESS FABRIC.

Specification of Letters Patent.

Patented Mar. 12, 1918..

Application filed December 8, 1913. Serial No. 805,264.

To all whom it may concern:

Be it known that I, JOHN L. TANDY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Wire Mattress Fabrics, of which the following is a specification.

This invention relates to wire mattress fabrics possessing the desirable quality of susceptibility of depression at one side without affecting the horizontalism of the other side, and my object is to produce a fabric of the character outlined which is economical in the use of material and of extremely simple construction.

With this object in view the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which,

Figure 1 is a fragmentary plan view of a wire fabric mattress embodying my invention.

Fig. 2 is an enlarged fragmentary perspective view of a modified design of the wire fabric.

Fig. 3 is a plan view of a second design of the wire fabric.

Referring now to the drawing in which like reference characters identify corresponding parts in all the figures, 1l indicate the end bars of a mattress frame, and 2 are longitudinally arranged coiled springs or helicals attached at their outer ends to the adjacent bars 1, each helical attached to one bar being longitudinally alined with a helical attached to the other bar.

The fabric is composed of longitudinal stays and cross links. The stays connect longitudinally alined springs or helicals and are held under tension thereby, and are each composed of longitudinally alined links 3 and plates arranged alternately. The cross links are arranged in rows also extending longitudinally of the fabric, all of the links in the same row being parallel and pivotally connecting plates 4 of adjacent stays. The links of some of the rows extend at unequal angles with respect to the adjacent stays. In Figs. 1 and 2 the links of certain rows extend obliquely and the links of other rows extend substantially at right angles to the stays, the links of some of the rows of oblique links occupying a converging relation. In Fig. 3, there are rows vof links'which extend at right angles to the stays and rows of links which extend obliquely to the stays.

The difference between Figs. 1 and 2, lies in the use of a greater number of rows of links which extend at right angles to the stays in the first-named figure than in the other figure. It will be apparent that many other modifications or designs of the fabric may be made without departing from the principle of construction involved, which is the use of rows of parallel links connecting adjacent stays, the links of some of the adjacent rows extending at unequal angles to the interposed stays. In the drawing are shown rows of links 5, extending at right angles substantially to the stays, and rows of obliquely arranged links. In Figs. 1 and 2, the obliquely arranged links of certain of the rows extend at equal but different angles with respect to the stays, and certain of the rows having parallel obliquely arranged links are numbered 6 and the remaining rows having links which extend at equal but difierent angles from the links 6 are numbered 7.

In Fig. 3 are shown rows of links 7 and 5 alternately arranged.

It will be apparent that the fabric may be made in many other forms or designs without departing from the principle of construction involved.

It is now evident from the foregoing description, that I have produced a mattress fabric which possesses the capacity for depression at one side without causing the other side to slope downward toward the depressed point; and this is true because there is no direct and continuous pull on the fabric for any material part of its width, that is to say, there is no continuous or unbroken transverse tension between all the stays and hence certain of the rows of the fabric may be depressed without materially affecting the remaining rows.

I claim:

1. A wire mattress fabric, comprising longitudinal stays, rows of parallel cross links at right angles to and connecting certain of the stays, and rows of wholly parallel links interspersed with the rows of cross links and extending at oblique angles to said stays.

A wire mattress fabric, comprising Genius at this patent may be obtained. for

rows of longitudinal stays, rows of nonflexible cross links extending at right angles to and pivotally connecting'certain of said stays, and rows of wholly parallel n0nflexible links at oblique angles to said stays and interspersed With and as rows parallel td the said rows of cross links.

3. A Wire mattress fabric, comprisingparallel rows of longitudinal links, plates pivotally connecting adjacent links of each row, parallel rows of cross links extending at right angles to the stay links, and pivotally connected at their ends to certain of said plates, and rows of Wholly parallel links interspersed with the said roWs of cross 15 JOHN L.
